PW has profiled thermostat to fit snuggly to curvature of pipe rather than a flat based thermostat

PW can be installed in a gentle evenly spaced helix or in a straight line

Assuming a minimum ambient temperature of -15°C and 20mm thick insulation a PW heating cable can be installed in a straight line along pipes up to 50mm diameter

Always select the shortest suitable cable from the PW range

Where the cable is longer than the pipe it is protecting wind the cable in a gentle, evenly spaced helix

Secure the cable to the pipe at 300mm intervals using Insulation tape

The entire installation including the thermostat should be covered with a maximum of 20mm thick flame retardant insulation

Ensure that the thermostat is positioned at the coldest end of the pipe

Plastic pipes should be wrapped in AL50 aluminium tape before installing the cable

When used with pipes that may be empty, the cable should be covered in a layer of TLAL50 aluminium tape before the installation is applied. A typical example would be when used with a condensing boiler

PW cables must not be exposed to temperatures in excess of 66°C

PFL warning labels should be applied to the outside of the insulation.
